Val Town Code SearchReturn to Val Town

211  Make an HTTP val (other vals are currently not supported to run, even though we have examples for them).
212  Start your response with a comment explaining how your approach will work, what libraries or 
213  API calls you will use, and any tradeoffs you're making. Then write the code in a consise way, 
214  the simplest way to achieve the goal, though you can add some inline comments to explain your 
215  reasoning (not for every line, but for major groups of lines). Don't use any environment variables 
216  unless strictly necessary, for example use APIs that don't require a key, prefer internal function 
217  imports (using esm.town), and prefer putting API keys as inline variables. Use built-in Deno 
218  functions where possible. Unless specified, don't add error handling, 
219  make sure that errors bubble up to the caller.
220  Avoid external images or base64 images, use emojis, unicode symtols, or icon fonts/libraries instead, unless that's
221  not practical for the user's request (e.g. if they ask for a particular animated gif).
222  If the user asks for something that requires persistence, use the Val Town Blob storage API, unless
223  explicitly specified otherwise. Use the current val name for the storage key, which you can get
224  using the "pomdtr/extractValInfo" val, which you can call like this:

391  ### Lower-level API
392  
393  We do provide access to the lower-level getter and setters, which are useful if you are storing non-JSON or binary data, need to stream in your response or request data, or do anything else lower-level.
394  
395  - \`async get(key: string)\`: Retrieves a blob for a given key.
396  - \`async set(key: string, value: string | BodyInit)\`: Sets the blob value for a given key. See [BodyInit](https://deno.land/api@v1.38.1?s=BodyInit).

6* Fork this val to your own profile.
7* Make a folder for the temporary vals that get generated, take the ID from the URL, and put it in `tempValsParentFolderId`.
8* If you want to use OpenAI models you need to set the `OPENAI_API_KEY` [env var](https://www.val.town/settings/environment-variables).
9* If you want to use Anthropic models you need to set the `ANTHROPIC_API_KEY` [env var](https://www.val.town/settings/environment-variables).
10* Create a [Val Town API token](https://www.val.town/settings/api), open the browser preview of this val, and use the API token as the password to log in.
